Adds two helper functions to `Selection`: * `overlaps`: tests whether two `Selection`s contain any ranges which overlap with each other * `without`: Computes a new `Selection` that is the set difference of two `Selection`s, i.e. everything in the first `Selection` with everything that overlaps in the second `Selection` removed, potentially leaving holes in the original ranges. It also fixes a bug with `Selection::contains`: it assumes that if the second `Selection` has a greater number of ranges than the first, then the first cannot contain the second; but this is false, since one range from the first could contain multiple smaller ranges in the second. |
